Mean platelet volume is the most valuable hematologic parameter in differentiating testicular torsion from epididymitis within the golden time.

ABSTRACT:

Background

We aimed to assess the diagnostic value of hematologic parameters in the differential diagnosis of testicular torsion and epididymitis within and after the golden time.

Methods

We retrospectively reviewed the records of 250 patients aged <25 years who were diagnosed with epididymitis (n=119) or testicular torsion (n=131). The characteristics and hematologic parameters of patients in the two groups were analyzed. Receiver operating characteristic (ROC) curves were used to assess the validity of hematologic parameters as differential diagnostic tools with respect to the golden time (defined as 6 h of symptom duration). Further, we evaluated the predictive factors associated with orchiectomy in patients with testicular torsion.

Results

The mean patient age was 14.4 years. Among patients with testicular torsion, 91.40% (53 of 58) underwent detorsion and orchiopexy within the golden time, whereas only 27.40% (20 of 73) of the affected testes were preserved after the golden time. Within the golden time, mean platelet volume (MPV) seemed to be the most valuable hematologic parameter [area under the curve (AUC) 0.855, 95% confidence interval (CI): 0.778-0.932]. In a multivariate analysis, symptom duration (symptoms beyond the golden time) was associated with orchiectomy in patients with testicular torsion.

Conclusions

MPV showed the greatest hematologic value in the early stage of testicular torsion and epididymitis, suggesting its potential use for the differential diagnosis of these two conditions within the golden time.

Project description:IntroductionSepsis is a public health problem due to its high prevalence and mortality. Mean platelet volume (MPV), a biomarker reported in routine blood counts, has been investigated and shows promise for determining fatal outcomes in septic patients.ObjectiveEvaluate whether the mean platelet volume (MPV) and mean platelet volume-to-platelet count (MPV/P) ratio are predictors of clinical severity and mortality in patients with sepsis.MethodsA prospective population cohort of 163 patients aged 18-97 years was recruited at the Intensive Care Unit of Pablo Arturo Hospital, Quito, Ecuador from 2017-2019 and followed up for 28 days. Patients were diagnosed with sepsis based on SEPSIS-3 septic shock criteria; in which the MPV and the MPV/P ratio were measured on days 1, 2, and 3. Sequential organ failure assessment (SOFA) score and presence of septic shock assessed clinical severity. Mortality on day 28 was considered the fatal outcome.ResultsThe average age of the patients was 61,15 years (SD 20,94) and female sex was predominant. MPV cutoff points at days 1, 2 and 3 were >9,45fL, >8,95fL and >8, 85fL; and (MPV/P) ratio >8, 18, >4, 12 y >3, 95, respectively. MPV at days 2 (9,85fL) and 3 (8,55fL) and (MPV/P) ratio at days 1 (4,42), 2 (4,21), and 3 (8,55), were predictors of clinical severity assessed by septic shock, which reached significance in the ROC curves. MPV and (MPV/P) ratio were also predictors of clinical severity determined by SOFA at days 1, 2, and 3, where higher values were observed in non-survivors reaching significance in all categories. MPV and MPV/P ratio at days 1, 2 and 3 were independent predictor factors of mortality using Cox proportional hazards model (HR 2,31; 95% CI 1,36-3,94), (HR 2,11; 95% CI 1,17-3,82), (HR 2,13; 95% CI 1,07-4,21) and (HR 2,38; 95% CI 1,38-4,12), (HR 2,15; 95% CI 1,14-4,06), (HR 4,43; 95% CI, 1,72-11,37) respectively.ConclusionsMPV and the MPV/P ratio are predictors of clinical severity and mortality in sepsis. The MPV and its coefficient are indicators of the biological behavior of platelets in sepsis. They should be considered as a cost-effective and rapidly available tool that guides the treatment.

Project description:INTRODUCTION:In testicular torsion, ischemia time from pain onset impacts testicular salvage. A tunica albuginea fasciotomy to relieve compartment pressure followed by a tunica vaginalis flap (TVF) may enhance salvage. OBJECTIVE:To define the optimal window of ischemia time during which TVF may be most beneficial to avoid orchiectomy. STUDY DESIGN:A retrospective cohort study of males presenting with testicular torsion at a single tertiary-care institution from January, 2003 to March, 2017. Ischemia time was defined as duration of pain from onset to surgery. Because TVF would be an option to orchiectomy, and it was found that ischemia time was longer in testicles that underwent orchiectomy, matching was performed. Cases of torsion treated with TVF were matched 1:1 with cases treated with orchiectomy on age at surgery, and ischemia time. Outcomes included postoperative viability, defined as palpable testicular tissue with normal consistency, and atrophy, defined as palpable decrease in size relative to contralateral testicle. Sensitivity analyses were performed restricting to the subgroups with postoperative ultrasound, >6 months' follow-up, and additionally matching for degrees of twist. RESULTS:A total of 182 patients met eligibility criteria, of whom 49, 36, and 97 underwent orchiectomy, TVF, and septopexy alone, respectively. Median follow-up was 2.7 months; 26% of patients had postoperative ultrasound (61% of TVF group). In the orchiectomy, TVF, and septopexy groups, respectively, median ischemia times were 51, 11, and 8 h, postoperative viability rates were 0, 86, and 95%, and postoperative atrophy rates were 0, 68, and 24%. After matching, 32 patients with TVF were matched to 32 patients who underwent orchiectomy. In the TVF group, postoperative viability occurred in 95% (19/20) vs 67% (8/12) of patients with ischemia times ?24 and >24 h, respectively. Atrophy occurred in 67% (12/18) vs 83% (10/12) of these same respective patients. Sensitivity analysis by ultrasound and longer follow-up found similar viability results, although atrophy rates were higher. Additional matching for degrees of twist showed lower viability and higher atrophy rates for increasing ischemia times. DISCUSSION:Patients who presented with testicular torsion with ischemia times ?24 h and who were being considered for orchiectomy may have benefitted most from TVF, albeit at high risk of atrophy. However, for ischemia times >24 h, TVF may still have preserved testicular viability in two-thirds of cases. A limitation was short follow-up. CONCLUSION:A TVF was a valid alternative to orchiectomy for torsed testicles, albeit with high testicular atrophy rates.
